使用日期时间转换器时,我在解析下面的JSON时遇到了麻烦。我理解" - "和" at"导致问题,但这是我在响应中的JSON,并且无法控制它。
"[{\"Desc\":\"Unacceptable Signal\",\"Station\":\"Test\",\"When\":\"Tuesday - 5/18/10 at 3:34 PM\"},{\"Desc\":\"Low Battery\",\"Station\":\"Test Unit (21261)\",\"When\":\"Wednesday - 3/30/11 at 12:34 AM\"}]"
我的模特是:
public class CurrentAlarms
{
public string Desc { get; set; }
public string Station { get; set; }
public DateTime When { get; set; }
public CurrentAlarms() { }
public CurrentAlarms(string desc, string station, DateTime when)
{
Desc = desc;
Station = station;
When = when;
}
}
我已尝试将其反序列化,如下所示,即使删除" at"在日期时间字符串中,但我仍然得到一个"字符串格式不正确"来自JSON.NET的例外。我很难找到其他解决方法。任何帮助将不胜感激!
json = json.Replace(" at ", " ");
var format = "dddd MM/dd/yy h:mm tt";
var dateTimeConverter = new IsoDateTimeConverter {DateTimeFormat = format};
var result = JsonConvert.DeserializeObject<ObservableCollection<CurrentAlarms>>(json, dateTimeConverter);
答案 0 :(得分:13)
public class CurrentAlarms
{
public string Desc { get; set; }
public string Station { get; set; }
[JsonConverter(typeof(InvalidDataFormatJsonConverter))]
public DateTime When { get; set; }
public CurrentAlarms() { }
public CurrentAlarms(string desc, string station, DateTime when)
{
Desc = desc;
Station = station;
When = when;
}
}
class InvalidDataFormatJsonConverter : JsonConverter
{
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
// implement in case you're serializing it back
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue,
JsonSerializer serializer)
{
var dataString = (string) reader.Value;
DateTime date = parseDataString;
return date;
}
public override bool CanConvert(Type objectType)
{
return true;
}
}
尝试在ReadJson上调试它并在那里解析日期 - 现在应该更容易了。
